Tkinter框架尺寸不匹配主窗口及搜索窗口输入问题求助

问题1：主窗口框架尺寸不匹配的修复 #

你设置的operations_frame和log_frame高度总和等于主窗口高度，但实际不匹配的核心原因：

1. Tkinter的Frame默认会根据内部控件自动调整大小（propagate=True），忽略手动设置的尺寸
2. grid布局未给行分配权重，框架无法填充整个单元格空间

修复修改点： #

# 主窗口设置行权重，按350:100的比例分配空间
self.root.grid_rowconfigure(0, weight=7)
self.root.grid_rowconfigure(1, weight=2)
self.root.grid_columnconfigure(0, weight=1)  # 让列填充整个宽度

# Operations frame 修改
self.operations_frame = tkinter.Frame(self.root, width=700, height=350, bg='#293556')
self.operations_frame.grid(row=0, sticky='nsew')  # 填充整个单元格
self.operations_frame.grid_propagate(False)  # 禁用尺寸自动调整，强制保持设置高度

# Log frame 修改
self.log_frame = tkinter.Frame(self.root, width=700, height=100, bg='#2E4583')
self.log_frame.grid(row=1, sticky='nsew')
self.log_frame.grid_propagate(False)

问题2：搜索窗口无法输入与布局混乱的修复 #

搜索窗口用了Label控件（只读，无法输入），且单列表局导致元素排版混乱。需要替换为标签+输入框的组合，用两列布局优化排版。

修复修改点（替换原search_details函数）： #

def search_details():
    if not self.window_already_open:
        self.window_already_open = True
        search_window = tkinter.Toplevel()
        search_window.title('Search options')
        search_window.geometry('350x200')  # 放大窗口适配布局
        search_window.resizable(False, False)
        search_window.configure(bg='#293556')

        search_window.grid_columnconfigure(1, weight=1)  # 让输入框列填充剩余空间

        # 文件路径：标签+输入框
        file_path_label = tkinter.Label(search_window, text="目标路径:", bg='#293556', fg='white')
        file_path_label.grid(row=0, column=0, sticky='w', padx=(15, 5), pady=(15, 0))
        file_path_entry = tkinter.Entry(search_window, width=30)
        file_path_entry.grid(row=0, column=1, sticky='ew', padx=(0,15), pady=(15,0))

        # 文件名：标签+输入框
        file_name_label = tkinter.Label(search_window, text="文件名:", bg='#293556', fg='white')
        file_name_label.grid(row=1, column=0, sticky='w', padx=(15,5), pady=(15,0))
        file_name_entry = tkinter.Entry(search_window, width=30)
        file_name_entry.grid(row=1, column=1, sticky='ew', padx=(0,15), pady=(15,0))

        # 扩展名：标签+输入框
        extension_label = tkinter.Label(search_window, text="扩展名:", bg='#293556', fg='white')
        extension_label.grid(row=2, column=0, sticky='w', padx=(15,5), pady=(15,0))
        extension_entry = tkinter.Entry(search_window, width=30)
        extension_entry.grid(row=2, column=1, sticky='ew', padx=(0,15), pady=(15,0))

        start_searching = tkinter.Button(search_window, text='Start searching', bg='#294F63', fg='white')
        start_searching.grid(row=3, column=0, columnspan=2, pady=(15,0))  # 按钮跨两列居中

        def on_window_close():
            self.window_already_open = False
            search_window.destroy()

        search_window.protocol("WM_DELETE_WINDOW", on_window_close)
